Patent ES-268678-A1 (ES)
Title: Process for preparing graft copolymers from linear amorphous non-crystallizable polymers of alpha-olefins or copolymers of alpha-olefins with each other and/or ethylene
Inventor: NATTA GIULIO
IPC: C08F8/06
Filed: 1961-06-28
Abstract: A process of peroxidizing linear, non-crystallizable polymers of alpha-olefins comprises subjecting an aqueous suspension of the polymer to the action of oxygen at 40 DEG to 200 DEG C. and under 1 to 20 atmospheres pressure. Polymers specified are derived from propylene, butene, methylpentene, hexene and mixtures thereof with each other or with ethylene. The oxygen may be air or an p oxygen/inert diluent mixture, and the water may contain surface active agents. The polymer may be swollen with an inert diluent. Graft copolymers may be obtained by treating the peroxidized polymers, preferably swollen in a solvent, with a monomer which is polymerizable by a free-radical mechanism, e.g. styrene, butadiene, isoprene or vinylidine chloride. The graft polymerization may be effected in water containing emulsifying agents, anti-foaming agents and colloids. In Example 6 the product of grafting butadiene on to an ethylene-propylene copolymer is stabilized with phenyl-b -naphthylamine and is vulcanized with the aid of stearic acid, zinc oxide, diphenylguanidine, N-oxydiethylene benzothiazole-2-sulphonamide and sulphur. Latices of the graft polymers are useful as paints, varnishes and sizes for fabrics. Specifications 810,023 and 856,733 are referred to.

Title: Metal casting apparatus with electromagnetic nozzle
IPC: B01F33/40
Filed: 1969-05-13
Abstract: The fluid switch controls the flow of a liquid from a funnel shaped receptacle and causes mixing of the liquid when the switch is in a "closed" position. The switch includes an air nozzle which extends into the receptacle and opens at a point adjacent a bottom outlet opening of the receptacle. The nozzle is adapted to direct an air stream toward and through the outlet opening to pre-empt liquid flow therethrough. A greater amount of air than is necessary to pre-empt flow of liquid through the outlet opening may be directed at the outlet opening so that the excess air bubbles through the liquid causing turbulence and mixing of the liquid prior to the "opening" of the switch.

Patent ES-393529-A1 (ES)
Title: Selective tint correction circuits
IPC: H04N9/64
Filed: 1971-07-22
Abstract: Tint correction is provided in a color television system by altering the phase of the color subcarrier reference signal before application of this signal to color demodulators. Phase alteration is accomplished by monitoring the chrominance signals prior to demodulation to determine whether they possess phase components about the flesh axis. If such components exist, the chrominance signal is vectorially added to the reference oscillator signal to provide a new phased oscillator signal which, when applied to the demodulators, causes them to provide color signals representative of flesh tone.

If the hydrophilic substance is non-acidic so it will not interfere with the reaction, it can even be present from the outset.
Patent ES-401260-A1 (ES)
Title: Oil gasification burner
IPC: F23N5/20
Filed: 1972-03-28
Abstract: In a burner in which oil is gasified by the heat of the incoming air for combustion, that air is heated upon start up by an electric heater and after the burner is running by heat from the products of combustion. Should the combustion air be inadequately heated during operation a lower limit switch actuates controls to energize the electric heater and simultaneously reduce the amount of air supply by a predetermined increment. This action is repetitious until there is sufficient change thereby caused in the oil/air ratio (due to the decreased air flow) to result in the temperature not dropping below the lower temperature limit. Should the combustion air be excessively heated an upper limit switch actuates controls which shut off the flow of oil and simultaneously increase the amount of air supply by a predetermined increment. When the temperature is reduced to within the normal range, the oil supply turns back on. Again, this action is repetitious until there is sufficient change thereby caused in the oil/air ratio (due to the increased air flow) to result in the temperature not exceeding the upper temperature limit.

Title: Method for underground storage of heavy flowable substances
IPC: B65G5/00
Filed: 1974-07-09
Abstract: A method for underground storage of heavy liquid substances, such as No. 2 heavy fuel oil, which solidify at normal storage temperatures, in a storage facility including a series of parallel underground galleries separated by protective piers, the galleries being closed at one of their ends adjacent to a working gallery and opening at their other ends into a common central channel communicating with the well being worked, and the beds of the galleries being in the same substantially horizontal plane. The fuel oil is conveyed into the galleries and solidifies. In order to take the stored substance out of the storage facility, a fluid which may be water with fuel oil trapped in a basin or a portion of the solidified mass of fuel oil itself is heated and then circulated over the surface of the mass of solidified fuel oil. The fuel oil is thus progressively liquefied and entrained in the flow of the fluid so that it may be pumped and taken out of the storage facility.

Title: Device for monitoring the flow in the air line of an air brake system on a railway vehicle
IPC: B60T17/22
Filed: 1974-11-22
Abstract: The pressure in an air line in an air braking system for a railway vehicle is controlled by an operator's brake valve which is also constructed to maintain the pressure therein. A pressure monitor is responsive to the pressure drop across a restrictor in the air line or in a supply line leading from a source of compressed air. A control line is connected to an energy source through a shut-off device operable by the pressure monitor and through a two-position switch to be connected to a monitor device for brake release operation or to a second monitor device for the flow of air in the air line caused by defects or application of the emergency brake. The shut-off switch will move to the energy passing position only when a certain pressure difference in the restrictor is excceded. The two-position switch is actuated by the operator's brake valve and connects the brake release monitor device to the control line only when the operator's brake valve is in its brake release position. Otherwise, the two-position switch connects the control line to the monitor device for defect-originated air flow.

Title: Surveying device
IPC: D01H13/14
Filed: 1975-09-03
Abstract: Apparatus for surveying the condition of roving is mounted on an automatic yarn knotting device movable along a spindle row in a textile machine having a drafting device for roving allocated to each spindle. When a roving breakage is indicated, the knotting device stops at the appropriate position and a first detecting device on a pivoted lever is moved to a position in which it checks the presence of roving passing through the drafting device. If there is no roving due to exhaustion of supply, no knotting is effected, but if roving is present the knotting device is prepared and a second lever moves a second detecting device to two output rollers for delivery of roving from the drafting device. If this second device detects no wrapping of roving on one of the two output rollers, the knotting process is initiated. If a wrapping is detected, a separating or pinching device, previously brought into operative position on the first lever, is actuated to interrupt the supply of roving to the drafting device and the yarn knotting device continues along the spindle row.

Patent ES-450357-A1 (ES)
Title: Non-woven support screen for mass transfer devices
IPC: D04H3/14
Filed: 1976-07-31
Abstract: An improved non-woven support screen for mass transfer devices including a first set of parallel spaced longitudinally extending filaments having a predetermined thickness or diameter and a second set of parallel spaced filaments obliquely arranged relative to the first set of filaments and having a predetermined thickness or diameter approximately 1/2 that of the first set of filaments to provide improved control of membrane distention for minimizing the masking of the membrane surface by preventing excessive distention in one plane, to reduce the volume of body fluid layer in the membrane (low prime), and provide improved mass transfer efficiency while maintaining gentle mixing of the body fluid. Moreover, the velocity gradient of the exchange fluid is enhanced by the limited space provided for the exchange fluid channels to significantly improve the scrubbing action of the exchange fluid on the membrane surface. Advantageously, the larger diameter of the filaments of the first set provides low operating fluid pressure within the membrane channels by allowing selective distention of the membrane.
